142 CLASSIFICATION OF THE FORMS OF THE PRINCIPLES. 
of the organic group, as, for example, geological subsidence, or causes 
resulting in transportation to an isolated position. 
Autonomic selection codperating with autonomic isolation produces 
autonomic generation; and heteronomic selection codperating with 
heteronomic isolation produces heteronomic generation. 
Autonomic election includes endonomic election, produced by the 
success of different acquired methods of dealing with the environment, 
and reflexive election, produced by the social promotion or suppression 
of individuals according to the success of their habits in relation to 
others of the same group. It is in contrast with heteronomuic election, 
which is determined by conditions outside of the organic group. 
Autonomic partition includes endonomic partition and reflexive 
partition, and secures the grouping of individuals as regards their 
habitudes, through the influence of activities that lie within each asso- 
ciating group. It isin contrast with heteronomic partition, which is 
the grouping of individuals as regards their habitudes, through the 
influence of activities in the environment. 
Autonomic partition combining with autonomic election produces 
autonomic association; and heteronomic partition combining with 
heteronomic election produces heteronomic association. 
Habitudinal intensification may arise from activities entirely within 
the group of organisms, of which social promotion and social suppres- 
sion* of habitudes are familiar examples, and the combined effects of 
these activities on the habitudes of the group is appropriately called 
autonomic election; but we need a term to designate the combined 
influence of autonomic election and autonomic selection, producing 
the intensification of inherited aptitudes, in addition to the intensifica- 
tion of acquired habitudes. Such a term is autonomic intensification. 
It signifies the molding of types by activities within the intergene- 
rating and associating group. Incontrast with autonomic intensifi- 
cation, we have intensification produced by the combined action of 
heteronomic election and heteronomic selection, which may appro- 
priately be called heteronomic intensification. 
The codperation of autonomic partition and autonomic isolation 
I call autonomic demarcation; and the codperation of heteronomic 
partition and heteronomic isolation I call heteronomic demarcation. 
The codperation of autonomic intensification with autonomic 
demarcation produces autonomic segregation; and the cooperation of 
heteronomic intensification with heteronomic demarcation produces 
heteronomic segregation. 
* Baldwin defines social suppression as ‘‘Suppression of the socially unfittest by 
law, custom, etc.’’ (See ‘“‘Social and Ethical Interpretations,” Appendix B.)
